Brief Introduction of Fluidized Bed Boiler

Circulating Fluidized Bed (CFB) boilers using fossil and renewable energy sources have been successful in operation for the last two decades and have become popular due to their impressive environmental performance as well as their fuel flexibility [6]. The particle density of CFB is lower than BFB, and the fluidization is also better.

OUTOTEC ENERGY SOLUTIONS

Our CFB boilers are widely used in metallurgical applica-tions as roasters. Because of their robust design, it is also possible to use petcoke and coal as primary fuels. Due to the low combustion temperatures in CFB boilers, plants can usually achieve low emission levels without additional flue-gas cleaning typically only limestone

DEVELOPMENTS IN FLUIDIZED BED CONVERSION DURING

Figure 1 shows how bubbling fluidized bed (BFB) was used first and how there was a transition to the development of circulating fluidized bed (CFB) boilers in the mid-1980s because of obvious drawbacks of BFB for combustion of coal [2]. However, BFB showed itself suitable for combustion and gasification of biomass and waste [3].
